Safety Instructions

General Precautions

• Always wear goggles or safety glasses. Refrigerant liquid and battery acid can permanently damage the eyes.

• Never operate the unit with the discharge valve closed. Never close the compressor discharge valve with the unit in operation.

• Keep your hands, clothing and tools clear of the fans when the refrigeration unit is running. If it is necessary to run the refrigeration unit with covers removed, be very careful with tools or meters being used in the area.

• Check the condition of the gauge manifold hoses. Never let the hoses come in contact with a fan motor blade or any hot surface.

• Never apply heat to a sealed refrigeration system or container.

• Fluorocarbon refrigerants produce toxic gases in the presence of an open flame or electrical arc. The gases are severe respiratory irritants capable of causing death.

• Firmly tighten all mounting bolts. Check each bolt for correct length for their particular application.

• Use extreme caution when drilling holes in the unit. The holes may weaken structural components.

Holes drilled into electrical wiring can cause fire or explosion. Holes drilled into the refrigeration system may release refrigerant.

• Use caution when working around exposed coil fins. The fins can cause painful lacerations.

• Use caution when working with a refrigerant or refrigeration system in any closed or confined area with a limited air supply (for example, a trailer, container or in the hold of a ship). Refrigerant tends to displace air and can cause oxygen depletion. This can result in suffocation and possible death.

• Use caution and follow the manufacturer’s suggested practices when using ladders or scaffolds.

Refrigerant Oil Precautions Observe the following precautions when working with or around refrigerant oil:

• Do not allow refrigerant oil to contact your eyes.

• Rubber gloves are recommended when handling Polyol Ester based refrigerant oil.

• Do not allow prolonged or repeated contact with skin or clothing.

• Immediately wash all exposed skin after handling refrigerant oil.

Use the following First Aid practices if needed.

Eyes: Immediately flush eyes with large amounts of water. Continue flushing for at least 15 minutes while holding the eyelids open. Get prompt medical attention.

Skin: Remove contaminated clothing. Wash thoroughly with soap and water. Get medical attention if irritation persists.

Inhalation: Move victim to fresh air. Restore breathing if necessary. Stay with victim until arrival of emergency personnel.

Ingestion: Do not induce vomiting. Contact a local poison control center or physician immediately.

Electrical Precautions The possibility of serious or fatal injury from electrical shock exists when servicing a refrigeration unit.

Extreme care must be used when working with a refrigeration unit that is connected to its power source.

Extreme care must be used even if the unit is not running. Lethal voltage potentials can exist at the unit power cord, inside the control box, inside any high voltage junction box, at the motors and within the wiring harnesses.

Precautions In general disconnect the units power cord before repairing or changing any electrical components.

Note that even though the controller is turned off, one of the phases is still live and represents a potential danger of electrocution Where turning of the unit is not possible (for example at voltage measuring or troubleshooting), follow safety precautions below.

• Turn the unit On/Off switch to Off before connecting or disconnecting the unit power plug. Never attempt to stop the unit by disconnecting the power plug.

• Be certain the unit power plug is clean and dry before connecting it to a power source.

• Use tools with insulated handles. Use tools that are in good condition. Never hold metal tools in your hand if exposed, energized conductors are within reach.

• Do not make any rapid moves when working with high voltage circuits. Do not grab a falling tool or other object. People do not contact high voltage wires on purpose. It occurs from an unplanned movement.

• Treat all wires and connections as high voltage until ammeter and wiring diagram show otherwise.

• Never work alone on high voltage circuits on the refrigeration unit. Another person should always be standing by in the event of an accident to shut off the refrigeration unit and to aid a victim.

• Have electrically insulated gloves, cable cutters and safety glasses available in the immediate vicinity in the event of an accident.

First Aid

IMMEDIATE action must be initiated after a person has received an electrical shock. Obtain immediate medical assistance.

The source of shock must be immediately removed. Shut down the power or remove the victim from the source. If it is not possible to shut off the power, the wire should be cut with either an insulated instrument (e.g., a wooden handled axe or cable cutters with heavy insulated handles). A rescuer wearing electrically insulated gloves and safety glasses could also cut the wire. Do not look at the wire while it is being cut.

The ensuing flash can cause burns and blindness.

Pull the victim off with a non-conductive material if the victim has to be removed from a live circuit. Use the victim’s coat, a rope, wood, or loop your belt around the victim’s leg or arm and pull the victim off.

Do not touch the victim. You can receive a shock from current flowing through the victim’s body.

Check immediately for the presence of a pulse and respiration after separating the victim from power source. If a pulse is not present, start CPR (Cardio Pulmonary Resuscitation) and call for emergency medical assistance. Respiration may also be restored by using mouth-to-mouth resuscitation.

Low Voltage

Control circuits are low voltage (24 Vac and 12 Vdc). This voltage potential is not considered dangerous.

Large amount of current available (over 30 amperes) can cause severe burns if shorted to ground. Do not wear jewelry, watch or rings. These items can shortcut electrical circuits and cause severe burns to the wearer.

Electrostatic Discharge Precautions Precautions must be taken to prevent electrostatic discharge while servicing the MP-3000a microprocessor and related components. The risk of significant damage to the electronic components of the unit is possible if these precautionary measures are not followed. The primary risk potential results from the failure to wear adequate electrostatic discharge preventive equipment when handling and servicing the controller. The second cause results from electric welding on the unit and container chassis without taking precautionary steps.

Electrostatic Discharge and the Controller

You must avoid electrostatic discharges when servicing the controller. Solid-state integrated circuit components can be severely damaged or destroyed with less than a small spark from a finger to metal object. You must rigidly adhere to the following statements when servicing these units. This will avoid controller damage or destruction.

• Disconnect all power to the unit.

• Avoid wearing clothing that generates static electricity (wool, nylon, polyester, etc.).

• Do wear a static discharge wrist strap (refer to Tool Catalog) with the lead end connected to the controller's ground terminal. These straps are available at most electronic equipment distributors. Do not wear these straps with power applied to the unit.

• Avoid contacting the electronic components on the circuit boards of the unit being serviced.

• Leave the circuit boards in their static proof packing materials until ready for installation.

• Return a defective controller for repair in the same static protective packing materials from which the replacement component was removed.

• Check the wiring after servicing the unit for possible errors. Complete this task before restoring power.

Welding of Units or Containers

Electric welding can cause serious damage to electronic circuits when performed on any portion of the refrigeration unit, container or container chassis with the refrigeration unit attached. It is necessary to ensure that welding currents are not allowed to flow through the electronic circuits of the unit. The following statements must be rigidly adhered to when servicing these units to avoid damage or destruction.

• Disconnect all power to the refrigeration unit.

• Disconnect all quick-disconnect wire harnesses from the back of the controller.

• Disconnect all wire harnesses from the Remote Monitor Modem (RMM).

• Switch all of the electrical circuit breakers in the control box to the Off position.

• Weld unit and/or container per normal welding procedures. Keep ground return electrode as close to the area to be welded as practical. This will reduce the likelihood of stray welding currents passing through any electrical or electronic circuits.

• The unit power cables, wiring and circuit breakers must be restored to their normal condition when the welding operation is completed.

Removing Refrigerant Properly Use a refrigerant recovery process that prevents or absolutely minimizes refrigerant escaping to the atmosphere. Fluorocarbon refrigerants are classified as safe refrigerants when proper tools and procedures are used. Certain precautions must be observed when handling them or servicing a unit in which they are used.

Fluorocarbon refrigerants evaporate rapidly, freezing anything they contact when exposed to the atmosphere in the liquid state. In the event of frost bite, attempt to protect the frozen area from further injury, warm the affected area rapidly, and maintain respiration.

• Eyes: For contact with liquid, immediately flush eyes with large amounts of water and get prompt medical attention.

• Skin: Flush area with large amounts of lukewarm water. Do not apply heat. Remove contaminated clothing and shoes. Wrap burns with dry, sterile, bulky dressing to protect from infection/injury. Get medical attention. Wash contaminated clothing before reuse.

• Inhalation: Move victim to fresh air and use CPR or mouth-to-mouth ventilation, if necessary. Stay with victim until arrival of emergency medical personnel.

MP-4000 Controller Specifications Temperature Controller:

Type

MP-4000 is a controller module for the Thermo King Magnum+ Unit. Additional requirements can be met by means of expansion modules. The MP4000 is solely responsible for temperature regulation of the reefer container, but other monitoring equipment can be used in conjunction with the MP 4000 - such as a chart recorder.

Version See controller identification decal Defrost Initiation:

Evaporator Coil Sensor

• Manual Switch or Demand Defrost Initiation: Coil must be below 18 C (65 F). Defrost cycle starts when technician or controller requests defrost initiation.

• Timed Defrost Initiation: Coil must be below 4 C (41 F). Defrost cycle starts 1 minute after the hour immediately following a defrost timer request for defrost initiation. For example, if the defrost timer requests a defrost cycle at 7:35, the defrost cycle will start at 8:01. Datalogger will record a Defrost event for each interval in which a Defrost cycle is pending or active (i.e. both the 8:00 and 9:00 data logs).

v

Demand Defrost

Demand defrost function initiates defrost when:

• Temperature difference between the return air sensor and defrost (evaporator coil) sensor is too large for 90 minutes

• Temperature difference between the supply air sensors and return air sensor is too large

Defrost Timer:

Chilled mode

Evaporator Coil Temperature must be below 5C (41 F) to activate the defrost compressor hour timer.

There is an interval set for defrosting, however, the defrost timer is built intelligent - it detects whether or not there is ice building up on the coil. If there is no ice building up on the coil, it extends the defrost interval, and if there is Ice building up earlier on the coil it reduces the defrost interval. The maximum interval is 48 hours.

Frozen mode Every 8 hours of compressor operation. Defrost interval increases 2 hours each timed defrost interval. Maximum time interval in Frozen mode is 24 hours.

Reset to Base Time Defrost timer resets if the unit is off more than 12 hours, setpoint is changed more than 5 C (9 F) or PTI pretrip test occurs.

Defrost Termination:

Defrost (Coil) Sensor

Chilled mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F).

Frozen mode: Terminates defrost when coil sensor temperature rises to 18 C (65 F).

Unit Description, Features & Options

Introduction This chapter will briefly describe the following items:

• General Unit Description.

• Standard Component Descriptions.

• Optional Component Descriptions.

General Description

MAGNUM units are all-electric, single-piece, refrigeration units with bottom air supply. The unit is designed to cool and heat containers for shipboard or overland transit. The unit mounts in the front wall of the container. Fork lift pockets are provided for installation and removal of the unit.

The frame and bulkhead panels are constructed of aluminum and are treated to resist corrosion. A removable evaporator compartment door provides service access. All components except the evaporator coil and electric heaters can be replaced from the front of the unit.

Each unit is equipped with an 18.3 m (60 ft.) power cable for operation on 460-380V/3 Ph/60-50 Hz power. The unit power cable is stored below the control box in the condenser section.

Each unit is equipped with 460-380V/3 Ph/60-50 Hz electric motors. An automatic phase correction system provides the proper electrical phase sequence for condenser fan, evaporator fan and compressor operation.

Figure 2: MAGNUM+ Unit

The MAGNUM+ container unit features the following components. Each component will be described briefly on the following pages.:

• Scroll Compressor

• Compressor Digital Control Valve

• Economizer Heat Exchange System

• Temperature Sensors

BEN074

• Fresh Air Exchange System

• Receiver Tank Sight Glass

• Evaporator Fans

• Condenser Fan Control

• Suction/Discharge Pressure Sensor (Optional)

• Remote Monitoring Modem (RMM, RMM+) (Optional)

• USDA Cold Treatment Temperature Recording (Optional)

• Advanced Fresh Air Management (AFAM) and Advanced Fresh Air Management Plus (AFAM+) (Optional)

Scroll Compressor The scroll compressor features a digital port and an intermediate suction port.

Digital Port

The digital port provides cooling capacity control. The digital port is located at the top of the scroll assembly on the compressor body. When energized, the Digital Control valve disengages the scroll set.

This reduces pumping capacity to zero.

Intermediate Suction Port

The intermediate suction port draws suction gas from the economizer heat exchanger into the scroll assembly of the compressor. The scroll seals off the suction port. This prevents economizer gas from leaking back to the main suction port. It also prevents the economizer gas pressure from influencing the cooling capacity of the unit evaporator (main suction gas pressure).

Figure 3: Scroll Compressor

MP-4000 Controller The MP-4000 is an advanced microprocessor controller that has been specially developed for the control and monitoring of refrigeration units. See “Controller Description and Operating Chapter” for more detailed information.

Power Module Fuses

The PM-4000 Power Module in the MAGNUM Plus unit uses Ultra Fast 20 amp fuses to protect the power module and are not interchangeable with the MP3000 MRB fuses. The fuses from the MP3000 MRB must never be used in the PM 4000 Power Module.

Part number for a PM 4000 Power Module fuse (FF 20 amp 500v and black fuse holder) is:

P/N 419286 Fuse & Holder Blk MP4000

Part number for the MP3000 MRB fuse (F 20 amp 500V and red fuse holder) is:

P/N 419318 Fuse & Holder Red MP3000

Fuse and fuse holder will be sold together as a kit. Individual fuse and holder part number for the MP3000 will supersedes to the kit number once inventory is used up.

Compressor Digital Control Valve The MP-4000 controller pulses the Compressor Digital Control solenoid valve between open and closed positions. This provides precise cooling capacity control. No pump down function or warm gas bypass control is used in conjunction with the Compressor Digital Control valve. See the “General Theory of Operation Chapter” for more detailed information.

Figure 6: Compressor Digital Control Solenoid Valve

Economizer Heat Exchange System An economizer heat exchange system replaces the conventional heat exchanger. The economizer Heat Exchange system subcools the liquid refrigerant before it reaches the evaporator expansion valve.

Subcooling liquid refrigerant increases the cooling efficiency and capacity of the evaporator. See the “General Theory of Operation Chapter” for more detailed information.

Figure 7: Economizer Heat Exchanger

Temperature Sensors Each sensor element is connected to a cable and packaged in a sealed stainless steel tube. The temperature signal from the sensor is transmitted through the cable. PT.1000 type temperature sensors are used to sense temperatures for the:

• Supply Air

• Return Air

• Evaporator Coil

• Condenser Coil

• Ambient Air

The compressor sensor is of Thermistor type and is located in the top cap of the compressor.

These sensors are field replaceable. Five sensor receptacles are provided; three USDA and one cargo temperature.

AXA0427

Fresh Air Exchange System The fresh air exchange system removes harmful gases from containers carrying sensitive perishable commodities. The fresh air vent is located above the control box. The fresh air vent is adjustable to accommodate a variety of frozen and chilled load operating conditions.

Receiver Tank Sight Glass The receiver tank contains a sight glass which has three small balls that indicate the level of refrigerant in the tank for checking the refrigerant charge. A moisture indicator in the sight glass changes color to indicate the level of moisture in the system.

Evaporator Fans MAGNUM models are equipped with either 2 or 3 evaporator fans. All models feature 2-speed motors.

The evaporator fans operate continuously to circulate air inside the container. The evaporator fans operate on:

• High and low speed for chilled cargo at setpoints of -9.9 C (14.1 F) and above

• Low speed for frozen cargo at setpoints of -10 C (14 F) and below

The evaporator fan low speed RPM is one-half the high speed RPM.

The controller determines evaporator fan motor speed based on the setpoint temperature and the Economy mode setting.

NOTE: If Non-Optimized mode is on:

• Chill Loads: Evaporator fans operate on high speed

• Frozen Loads: Evaporator fans operate on low speed

NOTE: If optimized mode is on:

• Chill Loads: Evaporator fans operate on high and low speed - depending on the need for cooling.

• Frozen Loads: Evaporator fans operate on low speed and stops when there is no need for cooling.

Condenser Fan Control The controller also uses a proportional-integral derivative algorithm to control the condenser temperature and ensure a constant liquid pressure at the expansion valve. The condenser fan operates continuously in high ambients. In low ambient conditions, the controller cycles the condenser fan on and off to maintain a minimum condenser temperature. The controller maintains a minimum 30 C (86 F) condenser temperature on Chill loads and a minimum 20 C (68 F) condenser temperature on Frozen loads.

USDA Cold Treatment Temperature Recording (standard)

The MP-4000 controller includes provisions for the use of three or four USDA sensors. These sensors allow temperatures in various areas of the load to be monitored and recorded for United States Department of Agriculture use in monitoring Cold Treatment shipments.

When USDA sensors are installed, the controller will automatically detect each sensor and activate data logging. However, the USDA Type screen in the Configuration menu must be set to the correct sensor setting and each USDA sensor must be calibrated to comply with USDA temperature recording requirements.

Condenser fan control is provided in software or by a Condenser Fan Selection switch or a Water Pressure switch. Starting April 2005 we have added a shutoff valve on the outlet tube of the water-cooled condenser.

Condenser fan switch is a software key. This switch is provided on the control box with the water-cooled condenser option. Place the Condenser Fan On/Off switch in the Water position for water-cooled condenser operation.

Figure 12: Water-Cooled Condenser/Receiver Tank

Air Ventilation Logging (AVL - Optional)

AVL is used for detecting and logging the fresh air exchange position on the manual fresh air vent.

The opening angle of the fresh air vent is converted to an output signal from approximately 2-5 volts.

The disk opening is detected in steps of 0-125, 150, 175, 215 and 225 m3/hr.

See “Air Ventilation Logging (AVL)” on page 112 for more information.

Advanced Fresh Air Management (AFAM) System (Optional)

An advanced microprocessor controlled fresh air management system provides programmable control of air exchange rate, programmable delayed vent opening, automatic closure of air exchange vent during low ambient conditions, and data logging of air exchange rate and vent opening delay interval.

The AFAM system includes a door control module, vent door and vent grille. The MP-4000 controller sends a communication signal to the door control module to position vent door to desired position. The controller can also be set to delay opening of fresh air vent for up to 48 hours (in 1 hour increments). This allows faster product temperature pull-down.

See “Starting the AFAM System” on page 114 for more information.

AFAM Operation

The system is pre-calibrated for air exchange rates of 0 to 225 m3/hr. (0 to 132 ft3/min.). The actual door position is based on the air exchange setting and the power supply frequency.

If the controller identifies a component failure during unit startup, an alarm is recorded in the controller display and data-logger memory. If a power loss occurs after the AFAM system is turned on, the controller automatically operates the vent door based on the previous AFAM Delay and AFAM Rate settings when power is restored.

Figure 13: AFAM System

AFAM Vent Door Assembly

A microprocessor controlled vent door provides programmable control of the air exchange rate. The vent door is adjusted to the desired position by a vent door motor and linkage assembly, shown in Figure 14.

The system is pre-calibrated for air exchange rates of 0 to 225 m3/hr. (0 to 132 ft3/min.). The use of the AFAM system should be established by the shipper.

The default setting for AFAM in the Setpoint menu is the last value set (Off, AFAM). The Fresh Air Vent Man submenu should be set to AFAM to control the vent door to the fresh air exchange rate setting.

If the controller identifies a component failure during unit startup, an alarm is recorded in the controller display and data-logger memory. If a power loss occurs after the AFAM system is turned on, the controller automatically operates the vent door based on the previous AFAM Delay and AFAM Rate settings when power is restored.

Advanced Fresh Air Management Plus (AFAM+) System (Optional)

The Advanced Fresh Air Management Plus (AFAM+) System provides programmable control of the CO2 level in the container. The controller can be set to control the CO2 level in the container from 0 to 25 percent. See “Advanced Fresh Air Management Plus (AFAM+) System” on page 117 for more information.

WARNING: After installing or servicing the AFAM door, remove all tools and install the vent grille before starting the AFAM system. Failure to replace the vent grille before turning the AFAM system on may result in personal injury or unit damage.
